To @ZZ wiz-kombat may Concern@ Be itknown that I, HARRY L. TUNEY,

a. citizen of the United Statee, residinget` Portland, in the bounty of Multnomh and Sttte of; Qregom/hizive invented new/wand usef'ul Improvements in Genred Loeolnotives, of which the following is a speo'ifeation.

A gearis fixedio'n the kshaft 23h57" of @key 28 and the gear eiirriesfthe" drivers of friction elfehes, :one having driving frictiony ,sur feefj engaging a friction,surfgeefeljon thew geg@ 19 and; the" other havirfgieii friction s'iieit-e''` V3o engaging friction sarde-e132 on" tiiffgeprj 20. bushings 2i: are? con? neeted'byf 'in21a which ie'pifovi'dedwth bueh-mfg. The 'pie y is recre wiiii-f'ihebsii-f- 21e at its outer end which meshes with an internal gear 21f journaled on the bushing. It will be understood that while but one pin 21a is shown in the section, Ordinarily three of these pins are used in the structure, each of which is provided with a gear 21" in mesh with the gear 21f. It will readily be seen, therefore, that by turning the gear 21 the pins may be adjusted so as to nicely adjust the friction surfaces and -maintain them in parallel. The gear 21f is locked in adjustment by a set screw 21g.

A iluidactuated device is used fork throwing the clutches and is as follows: The end of the shaft 23 is screw-threaded at 33 and a cylinder 34 hasits head screwed on the end of the shaft. A piston 35 operating in the cylinder has'its movement conveyed by pins 37 to the sleeve 25, the sleeve having a flange 38 through which thev pins 37 extend. A cover 39 is arranged on the cylinder anda port 39a extends through the covera-nd cylinder to the side of the cylin der next the shaft 23. A nozzle socket 40 is arranged inv the cover and a nozzle 41 extends into this socket. A port 42 extends fromv the socket to the outer end of the cylinder. The nozzle 41 is divided into two compartments 44y and 45 and the com partment 44 communicates through a port 46 through a ported channel ring 47 to the port 42, the ported channel ring permitting the turning of the nozzle while maintaining communication between the port 46 and port 42. A port 48 extends from the chamber 45 and communicates through a channeled port ring 48a with the port 39a, the channeled ring in this instance also maintaining comlmunication between the port 48 and the port 46 as the-cylinder rotates on the nozzle. A steam pipe 49 leads to the chamber 44 and a steam pipe 50 to the chamber 45. These steam pipeslead from the boiler with controlling valves actuated from the cab, the valves and valve actuating mechanisms not being shown. It will readily be seen thatwhen steam is thrown on the outer pari of the cylinder the clutch surfaces 30 and 32 are thrown into engagement and a driving connection is made between the gear 18 and the gear 27. On the. other hand, if

steamis put into the inner end of the cyl inder the clutch surfaces 30 and 32 are ree leased and the clutch surfaces 29 and 3l are thrown into engagement, thus vmaking a driving connection between the gear 14 and the gear 27 andfthese gear connections being of different gear ratios a different speed is given to the gear 27 with one connection than the other. It will benoted also that this shift in speed maybe readily .1

accomplished withoutl jar through the friction clutches While the. locomotive is moving through the fluid actuated clutch controlling mechanism.

The gear 27 meshes with a gear 51 on the drive shaft 6 and thus completes the train of gears between the crank shaft and the drive shaft.

What I 'claim as new is zl. In a geared locomotive, the combination of a frame; an engine mounted on one side of the frame; a longitudinal drive shaft at the opposite side of the frame; a gear connection between the engine and the shaft; and driving axles driven from the shaft.
